影响边坡排水系统质量安全因素的相对重要度分析

Analysis on Relative Importance of Factors Affecting Quality and Safety of Slope Drainage Systems

摘要:

为了对边坡排水系统的质量安全进行评价，以现浇钢筋混凝土排水沟为研究对象，选择了表观质量和强度质量作为一级指标，淤堵状况、最大裂缝开展宽度、变形量、侵蚀度、配筋数量和强度作为二级指标，采用粗糙集和条件熵相结合的方式，并结合现场技术检测数据完成指标分级与决策表构建，对各二级指标的相对重要度作出评价。结果表明，侵蚀度、淤堵状况是影响边坡排水系统质量安全的重要因素，为边坡排水系统的重点监测与维护提供了依据。

Abstract:

To evaluate the quality and safety of slope drainage systems, taking cast-in-place reinforced concrete drainage ditches as the research object, the apparent quality and strength quality are chosen as primary indicators, while the siltation status, the maximum crack width, deformation, erosion degree, reinforcement quantity, and strength are selected as secondary indicators. By combining rough set and conditional entropy, and incorporating on-site technical inspection data, the indicator grading and decision tables are constructed to evaluate the relative importance of each secondary indicator. The results indicate that erosion degree and siltation status are the important factors affecting the quality and safety of slope drainage systems, providing a basis for key monitoring and maintenance of slope drainage systems.
